Find the point on the line -3x+5y-5=0 which is closest to the point (-4,0). Please Help!
the slope of the given line is 3/5.
So, you want a perpendicular line through (-4,0). That line will be
y = -5/3 (x+4)
The two lines intersect at (-115/34,-35/34)
Now just find the distance between those two points
